The females vary somewhat as regards the amount of 

 creamy or buffish white on the wings. I suspect that these 

 differences are seasonal. 



24. Tachyris floresiana,) sp. n. 



A local representative of T. lyncida ; the males with the 

 dentated blackish border of primaries not reaching external 

 angle and that of the secondaries reduced almost to a line on 

 the upper surface ; on the under surface the outer borders 

 vary a good deal (probably seasonally) in width ; the second- 

 aries are more creamy than in T. lyncida. 



Expanse of wings, ^ 54-69 millim. 



The females above show a much smaller whitish patch 

 than any females of T. lyncida. 



Expanse of wings, ? 61-63 millim.

The males of this species nearly resemble those of T. flo- 

 resiana, but the secondaries on the under surface are suffused 

 towards the base with sulphur-yellow (in what I regard as 

 the wet-season form), the females being heavily suffused 

 with smoky brown.

We possess Dr. Moore's type and a similar male from 

 Formosa. It appears to me that the differences between the 

 typical forms are only seasonal ; at any rate they have no 

 specific value.
